There is not enough information to know how ashitaba might work. Some chemicals in ashitaba seem to work as antioxidants. Other chemicals might block secretions of stomach acid. But most research has been done on animals or in test tubes, not people.
There is not enough information available to know if ashitaba is safe.
Special Precautions & Warnings:Pregnancy and breast-feeding: Not enough is known about the use of ashitaba during pregnancy and breast-feeding. Stay on the safe side and avoid use.
The appropriate dose of ashitaba depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for ashitaba. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
